Non-mule is basically a non-starter for 'net content-related work
these days for precisely that reason.  I wouldn't have a problem with
moving it to a Mule package.

This doesn't belong in net-utils.  Nor does xml.el, for that matter.
We'll have to think about the implications of moving xml.el, but let's
not follow that precedent here.

The existing package that fits best is prog-modes, but that's not a
good idea because I expect there must be several of these guys around;
they should be collected in one, reasonably well-named place.  I
suggest consulting with Norbert, and Ville and Steve Youngs if they're
around, about creating a new package "web-content-modes".  (Probably
you can come up with a better name.  Maybe it should be "-utils" for a
collection of small things.)  Or if we've got other js-related
libraries, a javascript-modes package.
